The present invention relates to improvements in collapsible tube-like containers tor pastes which are provided with an outlet to expel portions of the contents by applying pressure on the tube wall.

An object of the present invention is to provide a. collapsible tube-like container having an elastic outlet through which portions of the contents can be expelled and after each expulsion the elastic outlet thereby seals itself automatisally.

Another object of the present invention is to provide a collapsible tube-like container preferably made entirely from a pliable elastic nonmetallic material of thermo-plastic nature, for example a vinyl resin, particularly polyvinyl chloride with a high content of plasticiser in which container the packed liquids or pastes are placed between two welded ends of a tubing, and an aperture is provided proximate one of the ends thereof.

A still further object of the present invention is to provide a tube-like container having one end of which is of a neck like formation and an aperture for expelling portions of the contents is provided proximate one end of the neck portion thereo! and whereby the contents may be expelled only when the neck portion is bent in a direction opposite to that of the aperture and pressure applied to the tube walls.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein-like symbols refer to like or corresponding parts throughout the several views,

form of collapsible tube-like container showing the upper portion thereof.

Referring more particularly to the drawings, Figures 1 and 2 illustrate a collapsible tube-like container constructed in accordance with the present invention wherein a container body of a pliable elastic non-metallic material of thermoplastic nature, generally designated at ll, one end of such container being welded as at it and the other end being welded as at it. It will be noted that a neck portion 13 is formed at the end portion i2, such neck portion is being pro vided with an aperture It.

It will be noted from Figure 2 that the neck portion i3 does not rise from a flat base but is welded about its medial portion and provides neck shaped housings at both sides of the weld. The aperture I I in the neck i3 is made at right angles to the longitudinal length of the neck It and such aperture or slit is not to exceed one half of the circumference of said neck. Apertures or slits it may be provided at both sides of the neck portion as desired. Such may be the case when the expulsion of the contents will occur only from that aperture opposite to that direction in which the neck is bent.

The container body il may be filled with any desirable liquid or paste like material i5 and may be emitted from the tube only when the neck portion thereof is bent as shown in Figure 2. Referring more particularly to Figures 3 and 4 there is illustrated a modified form of construction of the present invention wherein a plurality of neck portions l3 having apertures i4 is provlded. Also a flap portion 12 is provided for tions 13* are of a zig-zag construction.

aiding the rigidity of the neck portions l3 and which may incidentally act as an applicator for applying the contents of the tube H to the desired surface area. In Figure 4 the neck por- It will also be noted that a filling eyelet i6 is provided on the side of the tube ll for replenishing of the substance within the tube H. The plurality of neck portions aid materially in distribution of a predetermined amount of substance over an area governed by the width of the flap l2, whereas with the one neck form it may be desired to cover only a small area when only one pass over the same would be necessary, however, it may be desired to cover a greater area with only one pass of the tube over such area. It is with this in mind that applicant has provided the plurality of neck portions.

Referring more particularly to Figure 5, a fur- Figure 7 is a perspective view of a modified. 5t ther modified form of Figure 1 is illustrated wherein the flap portion 12 covers the entire width of the upper portion of the tube II and is provided with a fringed flap portion I! which aids in the application of the substance from the aperture 14 in the neck portion 13.

A further modified form of Figure 1 is shown in Figure 6 wherein a partition or wall It extends longitudinally of the tube 41' in such a way that two dissimilar substances may be carried within the one tube and that an aperture l4 may be applied to either side of the neck portion l3 for expelling the desired contents by bending the neck portion li of the tube in a direction opposite to that of the desired aperture.

In Figure 7 a modified form of the invention is shown wherein a bendable neck 13 is attached to the tube body II. A cap 2| is provided to protect the neck from being bent during transrt. It will be noted more particularly that the basic concept of the invention common to .all forms of the invention herein disclosed and described is the provision of a longitudinally extended narrow neck portion at the top of the tube wherein the neck portion I3 is narrower than the width of the tube I l and that such neck portion has been formed by a pressing and drawing action whereby the medial portion of the same is under great elastic strain thereby tending to afford extreme rigidity to the neck to resist any bending movement thereof. An aperture N or any suitable opening may be made in this neck portion. Under some conditions it is preferable to make such opening in the form of a slit whereby the longitudinal axis of such slit is at right angles to the longitudinal dimension of the neck and whereby upon bending the neck in a direction opposite to the side of the tube wherein the slit is made the contents l of the tube may be expelled by applying pressure about the walls of the tube H. The foregoing is more fully shown and will be more completely understood when read in connection with Figures 1 and 2.

While I have disclosed herein the best form of the invention known to me at the present time, I desire it to be understood that I reserve the right to make changes and modifications in the herein described embodiment of the invention provided such changes fall within the scope of the following claims.

What I claim is:

1. A collapsible tube-like container for pastes, the neck of which-is provided with a self-sealing aperture for permitting expulsion of the contents therethrough by application of pressure on the tube wall, wherein the tube neck is bendable and the aperture is made in the side wall thereof, through which aperture the contents are expelled by applying pressure on the tube wall and at '0 the same time bending the neck in opposite direction to the aperture.

2. A collapsible tube-like container for pastes as claimed in claim 1 wherein thebody and neck are of an elastic material.

3. A collapsible tube-like container as claimed in claim 1 wherein the aperture is a slit across the neck which slit is less than one-half the circumference of the neck.

4. A collapsible tube-like container as claimed in claim 1 wherein the tube is provided with a partition longitudinally therethrough and wherein apertures are provided at opposite sides of the neck whereby the contents of the tube on one side of the partition may be expelled by one aperture and the contents on the other side oi said partition by the other aperture.

5. A collapsible tube-like container as claimed in claim 1 wherein a welded flap surrounds the neck.

6. A collapsible tube-like container as claimed in claim 1 wherein the container is provided with a plurality of necks.

7. A collapsible tube-like container as claimed in claim 1 wherein the container is provided with a plurality of necks of zig-zag formation.

8. For use with a collapsible tube-like container an improved neck-like end receivable on said tube-like container, a slit in the side wall of said neck transversely thereof, the length of which is less than one-half of the circumference of said neck, said neck being elastic and bendable for emitting the contents of said container upon the simultaneous application of pressure on the side walls of the container and the bending of the neck in a direction opposite to the slit.

9. A collapsible container for pastes comprising a container body, and a container neck communicating with the body and bendable with respect thereto, said neck having a self-sealing aperture made in a side wall of said neck openable for expulsion of the contents of the container on application of pressure to the container body wall and simultaneous bending of the neck along a line coinciding with the aperture and opposite to the aperture.
